LTE TDD is a global standard for using unpaired spectrum for 4G networks. It has inherent interworking with LTE FDD networks and seamless integration with 3G networks. LTE TDD will be key to accessing higher spectrum bands above 3GHz and enabling technologies like carrier aggregation. It shares the same technology ecosystem and products as LTE FDD, including common chipsets, infrastructure and devices.

There is a TDD/FDD tradeoff—eventually most will deploy both
1 Assuming same transmit power . The main reason for reduced coverage is that the uplink device power is used part of the time for TDD but continuously for FDD . As an example, an 1:1 UL/DL allocation means a duty cycle of ~50% in the
uplink which contributes to a ~3dB reduced link budget

3.5GHz in the US defined as 3550 – 3650 MHz. In addition, Wi-Fi in unlicensed such as 2.4GHz, 5GHz (802.11 ac) and 60GHz (802.11 ad).
